WebFeb 17, 2024 · An SWR meter is a device that measures the standing wave ratio (SWR) of a radio signal. SWR is a measure of the efficiency with which an antenna or transmission line radiates or transfers power. The higher the SWR, the greater the loss of power. SWR meters are used to tune antennas and transmission lines.
